In-line ammeters (ammeters that must be connected directly into the line) that have multiple-range values cannot use a current transformer to provide the different ranges.

Question

Quizplus · Accepted Answer

In-line ammeters with multiple-range values can use shunts or other methods to extend their range, but they can also be designed to work with current transformers to provide different ranges, especially for high current measurements.
